Which is awesome, but then it shouldn't cost this much.
Unless if it's made of some of the actually ultra high performance plastics, like maybe polycarbonate or carbon fiber reenforced PA-6/PPA for example, but I highly doubt that's the case
Great for strength, bad for impact resistance. You'd want a non-filled material or at least less stiff filler. Something like aramid (kevlar) would give you good properties across the board for an application like this though.
It's true theoretically carbon fiber filling will always reduce Impact resistence, but it shouldn't be too much of an issue for this application when the polymer already have exceptional impact resistence and thus a lot of headroom to spare. In other words, because of how the polymers like PA/PC already have so much impact resistence, the stuff usually riot shield or motorcycle helmet shell is made of, there will still be more than enough impact resistence after the impact resistance reduction from CF filling, to be sufficiently impact resistent for a throwing mug LMAO
At least my power tools who's handles and casings are made of PA6 + 30% glass fiber (which has even worse impact resistence impact than CF) hold up more than sufficiently from getting thrown around lol
I have machined a lot, and I mean a lot of aramid filled materials of different kinds in a lot of situations. There is no way, under any circumstances I am letting that stuff near a drinking vessel I actively use, even if it is properly sealed. That shit is like hell on earth to be exposed to.
Fair, though I wasn't thinking of machining in this case. But yeah, my experience isn't generally related to food safe stuff, so I don't always think about it. Not too much concern about that on subs, helicopters, jets, etc.
Pa6 I believe. Food safe, microwave safe, etc.
But still plastic.
